近几年，我国轻集料砼小型空心砌块发展迅速，其年产量约达650万m3，占砌块总产量的22％左右。要保证质量和组织好轻集料砼小型空心砌块的生产，必须对轻集料及轻集料砼的特点和性能有所了解和认识，为此本文仅就这个问题谈谈自己的学习体会。用于配制砼的轻集料，以其位径大小 In recent years, China’s lightweight aggregates and small hollow blocks have developed rapidly, with an annual output of about 6.5 million m3, accounting for about 22% of the total block production. To ensure the quality and organization of the production of light aggregates and small hollow blocks, we must understand and understand the characteristics and performance of light aggregates and light aggregates. For this reason, this article only talks about their own learning experience. Lightweight aggregates for the preparation of niobium, with their size
